Abstract (en)
[origin: WO9422148A1] Audio signal cable for interconnecting a power source and a load, e.g. a power amplifier and a loudspeaker, wherein the geometry of the conductors (1, 2) and the dieletric (3) which separates them has been adapted to raise the capacitance and lower the inductance of the cable, therewith lowering its characteristic impedance to the same order as that of the load, typically 2-10 ohms. In a preferred embodiment this is done by providing a positive and a negative conductor (1, 2) each composed of a solid band of e.g. copper, substantially as wide as the cable which are sandwiched together with a thin interlayer of a dielectric material (3), e.g. polyester film.
